MUD-LUG Foa aurouonmnrmns.

Specification o! Letters Patent.

Patented Aug. 5, 1919.

Application led April 19, 1917. Serial No. 163,279.

To all whom. it may concern.'

Be it known that I, HALMER C. KrrrEL- soN, a citizen of the United States-{residingat Minneapolis, in the county of ennepin and State of Minnesota, have invented certain new and useful Im rovements in Mud- Lugs for Automobileires; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in mud lugs for automobile tires,\and more particularly to that type whichis detachable.

One object of my invention is to provide a mud lug formed of a single sheet of metal` having the central portion folded upon itself and extending outwardly and transversely to form a tranverse rib, and means carried by said sheet vwhich may be readily attached to a tire and detached therefrom.

Another object of' my invention is to pro vide a mud lug for an automobile tire which will be simple and durable, also which will be inexpensive to manufacture.

With these and other objects in view, the

invention consists of certain novel features' of construction, and the combination and arrangement of parts as will be more fully described and claimed.:-

In the acompanying drawings Figure 1 is a side elevation of my device as applied to a wheel;

Fi 2 is a vertical section on the line 2-2 of Fig. 1; Q

Fig. 3 is a top plan vlew of my devlce detached.

In carrying out my inventlon, I employ a lug A formed of a single sheet of metal 1 l which has its central portion folded upon itself and extends outwardly land transversely to form a transverse rib 2. The walls of ribV 2 are of a sufficient height to rovide a relatively lar vertical surface ibigripping sand or so mud. The rib 2 i projects at approximately right angles from the plate and has its walls 3 and 4 spaced apart. Rivets 5 'and 6 are passed through said walls 3 and 4 near the ends of the rib 2. The remaining portions of thesheet 1 are curved transversely as at 7 to cguform to the shape of the tire 8.

, A cha-in 9 is attached to the rivet and has its innei` link positioned between the walls 3 and 4 of the rib\ 2. A second chain 10 has its second link 11 attached to the rivet 5 and is positioned between the Walls 3 and 4 of the rib 2,while the first link 12'of the chain 10 extends laterally to the side. On the end of the chain 10 is a pin 13 which engages the link 12 when the lug A is in locked position about the, tire 8.

In operation, the lug A is placed about the tire 8 so that the outer face 14 of the tire 8 will engage the transversely curved end portions 7 of the sheet 1. The chain 9 is brought up under the tire 8 and felly 8', and the pin 13 is inserted throu h one of the links of the chain9 and forced ackward, until the link 12 engages the outer end of said pin 13. This will lock the lug A firmly about the tire 8. It is evident that there will be no binding of the parts about the tire when the lug is in position, as there is in most all other detachable mud lugs.

It will be noted that my device is much simpler in construction than other devices of its kind, as the body portion or sheet is stamped out of a single piece of metal, thus necessitating the minimum amount of labor. The manner in which the chains are placed in position insures a tight and permanent connection which cannot be broken or come loose while the lub is in position. The fact that the lug is of one piece of metal and is constructed as described, shows that it will be of very light material and will be easy to carry a set in the tool box of an automobile.

Various chan in the form, proportion and the minor etails of construction may be resorted to Without departing from the principle or sacrificing any of the advanta ofthe claimed invention.

claim 1. A mud lug formed of a sheet of metal having its central rtion folded upon itself transversely, said old extending outwardly at approximately right angles to form a transverse rib, said rib being of a sufiicient height to provide a relatively large side surface for gri pin sand or mud, the outer periphery o? sai rib extending across the tread surface of the tire, the remaining portions of said sheet being curved to conform to the shape of the tire, the walls of said rib being s aced apart, rivets passed through said wa ls near their outer ends, and means czn'ricd by said rivets :und arl-ungen wthn tho walls of Suid rib for securing the lng in position.

2. A traction lng comprising a bus-c adapted lo ht` onto u ll'o und having :L radially :nul hnnswrscly nlhposml lngr p1'opc1',tllccl\ls of which oxtvml nmtvrizllly beyond the sides of the i'n'c, mid hlg,r proper being Ushuped in cross Suction` :xml moans extending between the sido wulls of the lng proper outward of tho sdvs of thv lrv und attached thereto for :securing the traction lug on the h ixe.

In t'vsthnony whereof I have hereunto set my hund in the proscncu of two subscribing witnossos.
